As an oldie from the pre-PC generation it's paper and pen every time as it's the way I came through school and university. I couldn't type notes and still watch and follow the lecturer.

On courses I take lots of notes even when it's in a textbook, as I like it in my own words and all together. I keep an A4 hardback spiral bound notebook just for course notes and do refer back to it even after a couple of years.

And I hate cheap scratchy biros that stop working as the ball jams so it has to be one that flows properly and is comfortable to hold.
